Solidago gattingeriÌýChapman ex A. Gray is native to cedar barrens, limestone ledges and glades in central Tennessee and southern Missouri and adjacent Arkansas.Ìý It is adapted to seasonally dry habitats and can have shiny stems and leaves and phyllaries.Ìý The species has 5–8 ray florets and 3-9 disc florets ().Ìý In a multivariate study, Lopez Laphitz et al. (2011) found theÌýS. gattingeri,ÌýS. juncea, andÌýS. pinetorumÌýdiffered from the western three species of subsect.ÌýJunceaeÌý(S. confinis,ÌýS. guiradonisÌýandÌýS. spectabilis), but could be sometimes similar to each other on technical traits. Sample sizes were small and an expanded analysis would be useful. The species is diploid (2n=18) in central Tennesee. Semple (2023) mapped the limited data on the cytogeography ofÌýS. gattingeri.

Solidago gattingeriÌýwas included inÌýS.Ìýsubsect.ÌýJunceaeÌýby Semple and Cook (2006). Semple and Beck (2021) placed it as basal inÌýS.Ìýsubsect.ÌýRadulaeÌýfollowing the results of a polygenomic DNA study ofÌýSolidagoÌýand related genera (Semple et al. 2023).
